Thanks for verifying.

It looks like ac_abs_srcdir isn't calculated every time so I shouldn't 
be using it.
I changed the code to calculate the absolute location of 
srcdir/../config/default.mh
and verified the location got filled in for both the arm Makefile and 
arm/cpu_init Makefile
when configuring for arm-none-eabi and doing a make 
configure-target-libgloss.

I have checked in the new change.
